Thanks everyone for the replies !
The card is NOT compatible with Linux 2.6.11 and above as stated on the card's packaging.
Plus; the kernels that it is compatible with. Are only 32bit kernels.
SO I can get the card's driver and utilities to compile with 32 bit Slackware 13.1 and it's kernel 22.214.171.124-smp.
The card's module loads and reports the card. BUT neither the card's utilities nor Linux can find the ports on the card.
Possibly due to the motherboard/bios issue below.
I've discovered that with and without the card installed or module loaded. "lspci" lists the card.
I've also discovered that with and without the card installed. Dmesg is reporting serial and parallel ports.
EVEN THOUGH there are none in the computer !
I've also learned that my printer; Epson Stylus 88+ (?); will work when both it's parallel and usb connectors are in use.
And for the first time in my life. One of those usb-to-serial adapters actually works !
I've also tried installing a different add-on card. A PCIe USB 3 card.
I tried it in every slot. And it worked flawlessly.
So I can still use this new computer and all the other computers in my house with my printer.
And with the usb-to-serial adapter I will be able to use my old APC ups.
(yea I know I should upgrade all my computer crap. But I can only afford one piece of equipment at a time.)
So it looks like I had two things at play here.
1) A serial/parallel card that is not compatible.
2) A motherboard; ECS H61H2-WM; with a funky bios.
Thanks again for the replies !
